WPQRi

WPQRi is a specialized certification or qualification document used primarily within the welding and manufacturing industries to verify the qualifications of welders and welding procedures. The acronym "WPQR" stands for Welding Procedure Qualification Record, while the suffix "i" may denote a specific variation, designation, or related documentation within certain industry standards or organizations.

A WPQRti typically contains detailed information about the welding process, including the type of weld, materials used, welding techniques, testing methods, and the results of inspections and testing. It is an essential document that demonstrates a welding procedure's compliance with applicable codes and standards, such as those set by the American Welding Society (AWS), American Society of Mechanical Engineers (ASME), or other international standards.

The purpose of WPQRi is to ensure the quality, safety, and reliability of welded components by establishing and verifying that the welding procedures produce consistent and sound welds. It serves as a referenced document during the fabrication process, guiding welders and inspectors to adhere to qualified procedures.

Furthermore, WPQRi is often a prerequisite for a Welding Procedure Specification (WPS), which is used directly in production. The qualification process involves conducting test welds under specified conditions to prove that the procedure can reliably produce welds that meet strength and defect criteria.

In summary, WPQRi plays a vital role in maintaining quality assurance in welding operations, providing documented proof of procedure qualification that aligns with industry standards and regulatory requirements.
